I have an 80 CJ7 with a Ford 302 engine that has started to cut out when accelerating. The tach will goes to zero, the hiccups until I let off the gas then it goes back to normal until I need to accelerate again. I'm on my 3rd fuel pump which is a carter electric pump with a new filter before and after the pump. I check the MSD ignition control mod inside the distributor and it check ok. The MSD Distributor cap and rotor button are good too. The Engine Control module was replaced 8 months ago. I'm going nuts trying to figure out the problem here.

Since the 302 has the distributor in the front you might want to check the wiring going to it.
Could be that when you press the peddle moving throttle linkage that something is contacting a wire.
Look under the hood and under the dash.

Ok back on the road! The cutting out was a loose wire at the distributor and the vacuum advance was shot. I've also had fuel delivery issues which looks like the the tank needs to be cleaned out. The power of converting from 2barrel to a four barrel carb is amazing! Back to loving my jeep!

I'm glad you found the culprit I was also going to mention moisture in the dizzy, this was a common problem on my '69 Buick GS400

with a forward mounted distributor. In their wisdom, Buick placed the drains for the hood scoops right above the distributor. The trick was to squirt some WD40 into the cap.

Now since everything engine wise is doing good i'm back to having fuel pump problems. I'm using a Carter inline Solenoid style universal pump. It does good for a trip then it just quits pumping! I carry a spare bump you let the pump cool down and blow thru both sides and it starts pumping good again. The PO put the pump on the passenger side fender well and I'm thinking I should move it to the back of the jeep on the frame. Thoughts??
